This is a combo pack of interactive projector sources.  It comes with a rack mount bracket, USB interactive stick and some other cool bonus GEAR we love.  For a better price, log in as a CollabRjabbR Member and nav to the Marketplace. FYI this is a TIER2 Kit.  There is nothing we like as TIER Free and TIER ONE Touch-Screens are still priced astronomically.  Keep checking back here for updates.
